Yeah, for casual prints I use a non-photo-specific printing shop too. More cost effective, plus you can print more, rotate the images more often, etc. Non-archival quality large format inkjet prints. Recommended to a couple of friends too. If I recall correctly, A3 approx $4-$6, A2 approx $8-$12. Options of matt/gloss lami, mounting etc. (Disclaimer: Prices are guesstimates only, been awhile since I last went). Visual Hub @ Sunshine Plaza: Visual Hub @ Sunshine Plaza
I did mine in ubi. Super fast. But definitely not for fine art or archival.
